I noticed more problems: arrow directions are inverted - when an outline
is hidden the arrow direction is open; when it's shown then the button has
the closed state.
S-TAB (outline-cycle-buffer) is very slow: takes ~3 seconds on a small
NEWS buffer.
Also don't understand why is this change:
(when outline-minor-mode-highlight
- (if (and global-font-lock-mode (font-lock-specified-p major-mode))
- (progn
- (font-lock-add-keywords nil outline-font-lock-keywords t)
- (font-lock-flush))
- (outline-minor-mode-highlight-buffer)))
+ (when (and global-font-lock-mode (font-lock-specified-p major-mode))
+ (font-lock-add-keywords nil outline-font-lock-keywords t)
+ (font-lock-flush))
+ (outline-minor-mode-highlight-buffer))
`outline-minor-mode-highlight-buffer' is intended only for buffers
that don't support font-lock highlighting.

It would be nicer if the color of the button depended on the outline's color,
e.g. blue for the top-level blue outline face, etc.

Since outline-minor-mode-use-buttons uses buffer-match-p, it can have
any condition, including a condition to exclude etc/NEWS, for example.
